Product Description

MgAl2O4 Magnesium aluminate (spinel) single crystal is widely used in acoustic and microwave devices and fast IC epitaxial substrate.

Main Features

Magnesium aluminate (MgAl2O4) exhibits good lattice matching with epitaxial silicon films.

The self doping amount of aluminum atoms in the epitaxial silicon thin layer is small, the thermal stability is good, the expansion coefficient of silicon is relatively close, the hardness is small, and the processing performance is good.
